    Abstract: An analytical cell assembly comprising a base with a radiation source mounted on one end, an enclosure on the other end, and a cell proper, with cell heating means, within the enclosure. The enclosure and cell have cooperative fluid flow connections whereby the cell is modular and may be simply lifted out of the enclosure. The enclosure also includes a collimating lens assembly interposed between the cell within the enclosure and the source outside the enclosure on the base. The entire assemblage of source, enclosure and cell can be moved as a unit, making it modular, or just the cell can be moved as a module leaving the enclosure and the source in place in an instrument using the invention cell assembly.

    Abstract: A modular system for performing optical spectroscopy measurements comprising enclosed modules with ports through which optical beams may pass into and out of the modules. The modules may be joined together with the ports aligned and are interchangeable in the sense that the focal point of the optical beam directed out of any output port has the same location relative to the output port.

    Abstract: A method and apparatus for measuring light reflectance, absorption and/or transmission having a plurality of light emitting diodes (LEDs) arranged to direct light emissions toward a test piece, with the various diodes being selected to emit light of different wavelengths and at least one light-responsive sensor disposed to receive light reflected and/or transmitted by the test piece and originating with each of the light-emitting diodes. Electrical drive circuit means are provided for alternately or sequentially energizing the plurality of LEDs of different wavelengths, such that the reflected or transmitted light received by the sensor is a function of the various wavelengths of the respective LEDs. In one embodiment, the sensor is operative to generate an output signal indicative of the characteristics of the test piece as a function of the different wavelengths of the LEDs which signal is processed to provide a display of the ''''differential'''' light reflectance, transmission and/or absorption characteristics of the workpiece and the wavelengths of the LEDs. In another embodiment, a plurality of LEDs each having a different frequency is operative to generate a range of signals which provide a measurement of reflectance, transmission and/or absorption as a function of the wavelengths of the various LEDs employed. The plurality of LED sources and the sensor may be mounted within a self-contained module which may be detachably connected to an instrument housing containing the drive and output circuitry and display means, such that a number of different source modules may be provided each having LEDs of unique wavelength with the various modules being interchangeable to permit a wide variety of measurement frequencies.

At least either the illumination module (1) or the detection module (4) is optically conjugate with the scanning/injection module (2) via a conjugating optical fibre (5, 7). The use of conjugating fibres (5, 7) enables the maintenance, repair and updating of the device to be improved. It also enables modal filtering of the excitation beam to be carried out and ensures that the device is confocal.

    Abstract: A multichannel fluorosensor includes an optical module and an electronic module combined in a watertight housing with an underwater connector. The fluorosensor has an integral calibrator for periodical sensitivity validation of the fluorosensor. The optical module has one or several excitation channels and one or several emission channels that use a mutual focusing system. To increase efficiency, the excitation and emission channels each have a micro-collimator made with one or more ball lenses. Each excitation channel has a light emitting diode and an optical filter. Each emission channel has a photodiode with a preamplifier and an optical filter. The electronic module connects directly to the optical module and includes a lock-in amplifier, a power supply and a controller with an A/D converter and a connector. The calibrator provides a response proportional to the excitation intensity, and matches with spectral parameter of fluorescence for the analyzed fluorescent substance.
